Logic Gates

AND Gate

Only TRUE when TRUE & TRUE

OR Gate

TRUE when either is TRUE

NOT Gate

Opposite of everything

NAND Gate

Not and

NOR Gate

Not or

XOR Gate

Exclusive or gate

Two digit adder

Boolean in Python

Equal

1 == 1 # compares two things to each other x = 1 # assigns the value 1 to the variable x

If statements

if condition: # if the condition is true do something # do this stuff

Else if statements

elif condition: # done if the "if" statement is false # check if the condition is true do something # do this stuff

Else statements

else: # if all the if and elif statements are false do this stuff

Loops

While loop

while condition: # while this condition is true do this # do this stuff

• NOTE: Use while true with extreme caution, generally not recommended unless you are working with physical components
• use "break" to exit a while loop, or change the condition to be false

For loop

for x in range (y,z): do stuff # repeats the "do stuff" for z-y times

• create an iterator, and the iterator increases by 1 each time
• repeat as long as iterator is in range
• used to specify if you want to repeat something for a set amount of times

Sample solution to the final game

Homework

Challenge you parents to play the game, then ask for their feedback.
